The type 'T' cannot be used as type parameter 'T' in the generic type or method

Question

I have the following method:

protected T AttachComponent(){
    T gsComponent = gameObject.GetComponent();
    if(gsComponent == null){
            


        

Answer 1

The issue is that the AddObject method returns a Component. You need to tell the compiler that your T is actually a type of Component.

Attach a generic constraint to your method, to ensure that your Ts are Components

protected void AttachComponent<T>() where T : Component
{
    // Your code.
}
